Arrest the Taxpayers' Alliance!

It appears that the Taxpayers' Alliance has been using its charitable arm for funding which would seem in breach of charitable law (this from the Guardian). It would also mean that the TA is being funded by the taxpayer as it is using Gift Aid to boost its income.

So not only is the TA hypocritically using taxpayers' money while campaigning for lower taxes, it is sucking cash away from health, education, policing etc. The Charities Commission is investigating, but this is surely a matter for the police? As charities are not allowed to be involved in political campaigning and the TA is clearly linked to the Tories, this is surely tax fraud?
